The manga's story begins when Emma, a 30-year-old woman, loses her love life, job, and home in one fell swoop, as the boyfriend she was living with breaks up with her on the same day the company she was working for goes bankrupt. She wanders into a mansion, and is soon found by its owner Chloe, an eccentric rich heiress who lives alone. While Chloe initially accepts Emma staying at her mansion for a night, an unfortunate fire at Chloe's home that night forces them to find a living situation together. Later, a customer arrives at Chloe's fortune telling shop and brings mysterious circumstances that the two get drawn into.
